DETAILED DESCRIPTION OF THE INVENTION

[0022] Reference will now be made in detail to the subject matter disclosed, which is illustrated in the accompanying drawings.

[0023] Before explaining one or more embodiments of the disclosure in detail, it is to be understood the embodiments are not limited in their application to the details of construction and the arrangement of the components or steps or methodologies set forth in the following description or illustrated in the drawings. In the following detailed description of embodiments, numerous specific details may be set forth in order to provide a more thorough understanding of the disclosure. However, it will be apparent to one of ordinary skill in the art having the benefit of the instant disclosure the embodiments disclosed herein may be practiced without some of these specific details. In other instances, well-known features may not be described in detail to avoid unnecessarily complicating the instant disclosure.

[0024] As used herein a letter following a reference numeral is intended to reference an embodiment of the feature or element that may be similar, but not necessarily identical, to a previously described element or feature bearing the same reference numeral (e.g., 1, 1a, 1b). Such shorthand notations are used for purposes of convenience only and should not be construed to limit the disclosure in any way unless expressly stated to the contrary.

[0025] Further, unless expressly stated to the contrary, "or" refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).

[0026] In addition, use of "a" or "an" may be employed to describe elements and components of embodiments disclosed herein. This is done merely for convenience and "a" and "an" are intended to include "one" or "at least one," and the singular also includes the plural unless it is obvious that it is meant otherwise.

[0027] Finally, as used herein any reference to "one embodiment" or "some embodiments" means that a particular element, feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment disclosed herein. The appearances of the phrase "in some embodiments" in various places in the specification are not necessarily all referring to the same embodiment, and embodiments may include one or more of the features expressly described or inherently present herein, or any combination of or sub-combination of two or more such features, along with any other features which may not necessarily be expressly described or inherently present in the instant disclosure.

[0028] FIGS. 1A-1F in general illustrate an aircraft cabin 100 including an aircraft seat 102, in accordance with one or more embodiments of the disclosure. For example, the aircraft seat 102 may include, but is not limited to, a business class or first-class passenger seat, an economy-class passenger seat, a crew member seat, or the like. It is noted the terms "aircraft seats" and "passenger seats" may be considered equivalent, for purposes of the disclosure.

[0029] The aircraft seat 102 may be rotatable about an axis (e.g., swivelable). The aircraft seat 102 may be fully positionable between the outer limits of motion as defined by the moveable components of the aircraft seat 102. Where the aircraft seat 102 is installed within a passenger compartment, the aircraft seat 102 may be fully positionable between the outer limits of motion as defined by one or more passenger compartment monuments of the passenger compartment. It is noted an upright or raised position may be considered a taxi, takeoff, or landing (TTL) position during select stages of flight (though the upright or raised position is not limited to use during the select stages of flight as the TTL position, but also may be used at any point during the flight), for purposes of the present disclosure. In addition, it is noted that any position that does not meet the above-defined requirements of the TTL position may be considered a non-TTL position, for purposes of the present disclosure. Further, it is noted the aircraft seat 102 may be actuatable (e.g., translatable and/or rotatable) from the TTL position to a non-TTL position, and/or vice versa. Further, it is noted the aircraft seat 102 may be capable of a fully upright or raised position, and that the TTL position may have a more reclined seatback cushion and a more angled upward seat pan cushion as compared to the fully upright or raised position. Therefore, the above description should not be interpreted as a limitation on the present disclosure but merely an illustration.

[0030] In general, an aircraft seat 102 may be translatable (e.g., trackable or slidable). The aircraft seat 102 may be rotatable about an axis cross-wise through the aircraft seat 102 into a position including, but not limited to, the upright or raised position, one or more lounge or reclined positions, and a lie-flat or bed position. For example, the aircraft seat 102 may transition directly between the upright or raised position and the lie-flat or bed position. By way of another example, it is noted the aircraft seat 102 may transition through one or more lounge or reclined positions between the upright or raised position and the lie-flat or bed position. By way of another example, the aircraft seat 102 may transition into one or more lounge or reclined positions in a motion separate from the transition between the upright or raised position and the lie-flat or bed position. Therefore, the above description should not be interpreted as a limitation on the scope of the disclosure but merely an illustration.

[0031] The aircraft seat 102 may include a seatback 104 (or primary seatback 104). The aircraft seat 102 may include a seat pan 106 (or primary seat pan). The aircraft seat 102 may include one or more armrests 107. For example, as will be discussed further herein, the one or more armrests 107 may include one or more deployable armrest assemblies 108. The aircraft seat 102 may be coupled to a base 110. The base 110 may be covered by a shroud. For example, the shroud may include one or more sections configured to cover at least a portion of the aircraft seat 102. For instance, the shroud may include a bucket shroud section and a base shroud section. It is noted, however, that the shroud may be formed from one piece (i.e., includes a single section).

[0032] For purposes of the present disclosure, it is noted herein that the "seatback 104" or "primary seatback 104" and the "seat pan 106" or "primary seat pan 106" may be referred to collectively as "the primary section" and the "auxiliary seatback portion 114" and "auxiliary seat pan 115" may be referred to collectively as the "the auxiliary section", which together form the wide seating area 116.

[0033] The seatback 104 may include a headrest 112. For example, the headrest 112 may be integrated within the seatback 104. By way of another example, the headrest 112 may be a separate component coupled to (or inserted into) the seatback 104. For instance, the headrest 112 may be movable relative to the seatback frame of the aircraft seat 102 (e.g., adjustable, removable, or the like).

[0034] The seat pan 106 may be coupled to the seatback 104, such that actuation of one may cause a corresponding actuation of the other. For example, the seat pan 106 may be coupled to the seatback 104 via one or more pivot joints. For instance, the seatback 104 may be configured to rotate about an axis through a pivot joint coupling the seatback 104 and the seat pan 106 during actuation between the upright position and the lie-flat or bed position.

[0035] The aircraft seat 102 may include a seat frame. The seat frame may include, but is not limited to, a seatback frame, a seat pan frame, and a base assembly.

[0036] One or more of the seatback frame and/or the seat pan frame may be directly coupled, or indirectly coupled via one or more interconnecting components, to one or more components of the seat frame. At least a portion of the shroud (e.g., the bucket shroud section of the shroud) may be configured to cover the seat pan frame.

[0037] The aircraft seat 102 (e.g., the base 110, as illustrated in FIG. 1A-1E) may include a base assembly. The base assembly may include one or more base rails (e.g., tubes, bars, or the like). For example, the one or more base rails may be positioned relative to a particular direction of travel of the aircraft seat 102 including, but not limited to, perpendicular (e.g., cross-wise), parallel (e.g., cross-wise), or the like. For instance, the one or more base rails may be positioned relative to a same or a different direction of travel of the aircraft seat 102.

[0038] The base assembly may include one or more base brackets. For example, the one or more base rails may be coupled together via the one or more base brackets. For example, a base bracket may couple together the base rail and an adjacent base rail at any angle, such that the base assembly may include an outline of any geometric shape known in the art. For instance, the outline may be rectangular or substantially rectangular. Therefore, the above description should not be interpreted as a limitation on the present disclosure but merely an illustration.

[0039] The one or more base brackets may be coupled to a set of floor tracks of the aircraft cabin 100 via one or more floor fittings. At least a portion of the shroud (e.g., the base shroud section of the shroud) may be configured to cover the base assembly.

[0040] Referring to FIGS. 1B-1C, the aircraft seat 102 may include the one or more deployable armrest assemblies 108. In embodiments, as shown in FIG. 1B, the aircraft seat 102 may include a single deployable armrest assembly 108. For instance, the deployable armrest assembly 108 may be coupled to a side of the seat pan 106. In one instance, the deployable armrest assembly 108 may be coupled to a right side of the seat pan 106. In another instance, the deployable armrest assembly 108 may be coupled to a left side of the seat pan 106.

[0041] In embodiments, as shown in FIG. 1C, the aircraft seat 102 may include a plurality of deployable armrest assemblies 108. For example, the plurality of deployable armrest assemblies 108 may include a first deployable armrest assembly 108 and an additional deployable armrest assembly 108. In one instance, the first deployable armrest assembly 108 may be coupled to a first side of the seat pan 106 and the additional deployable armrest assembly 108 may be coupled to an additional side of the seat pan 115. In this regard, as shown in FIG. 1C, the first deployable armrest assembly 108 may be coupled to the right side of the seat pan 106 and the additional deployable armrest assembly 108 may be coupled to the left side of the seat pan 106.

[0042] In embodiments, the deployable armrest assembly 108 may be configured to actuate between one or more positions, as will be discussed further herein. For example, the deployable armrest assembly 108 may be configured to actuate between one of a stowed position and a deployed position, and vice versa. In one instance, when the deployable armrest assembly 108 is in the stowed position (e.g., the position of the deployable armrest assemblies 108 as shown in FIG. 1A), the deployable armrest assembly 108 may provide the passenger with an armrest (i.e., a place for the passenger to rest their arm). In another instance, when the deployable armrest assembly 108 is in the deployed position (e.g., the position of the deployable armrest assemblies 108 as shown in FIG. 1C), the deployable armrest assembly 108 may act as an auxiliary seat pan 115 to form a wide seating area 116 (or wide seating surface). The wide seating area 116 may be configured to seat one or more passengers. For example, the primary seat section (e.g., seatback 104, seat pan 106) may be configured to seat a passenger occupying the aircraft passenger compartment suite. By way of another example, the auxiliary section seat (e.g., auxiliary seatback portion 114, auxiliary seat pan 115) may be configured to seat a guest passenger when the aircraft seat 102 is in the upright position. Further, the wide seating area 116 may provide an area to be used as a surface for the passenger's belongings or provide increased width for portions of a passenger's body.

[0043] The auxiliary seat pan 115 may be substantially flush (substantially parallel, e.g., sit level at the say height) with the primary seat pan 106, such that the auxiliary seat pan 115 and the seat pan 106 may form a substantially flush, continuous bench surface, or wide seating area 116.

[0044] It is noted that the actuation of the auxiliary section may be independent of the actuation of the primary section.

[0045] It is noted that the increased width of the aircraft seat 102 may provide for the aircraft passenger compartment suite to be used as a shared social environment in addition to usage by the passenger occupying the aircraft passenger compartment suite.

[0046] Referring now to FIGS. 1E-1F, the deployable armrest assembly 108 may include a housing configured to house (or at least partially enclose) an armrest attaching panel 122 and an actuator sub-system 120. For example, the housing may include a stationary housing portion 109 and a deployable housing portion 111. In this regard, the stationary housing portion 109 and the deployable housing portion 111 may be configured to house (or at least partially enclose) the armrest attaching panel 122 and the actuator sub-system 120.

[0047] In embodiments, the deployable housing portion 111 may be configured actuate between one of a stowed position and a deployed position, and vice versa. The deployable housing portion 111 may consist of a similar or different material of the seat pan material (e.g., fabric, leather, or other material used for aircraft seating). In embodiments, the stationary housing portion 109 may be configured to remain in place (e.g., not actuate) when the deployable housing portion 111 actuates between the stowed position and deployed position.

[0048] In embodiments, the stationary housing portion 109 and the deployable housing portion 111 may be separated by a division line 113 (or divider line 113). For example, the deployable housing portion 111 may be arranged above the division line 113, such that the stationary housing portion 109 is arranged below the deployable housing portion 111. Although FIGS. 1E-1F depict the housing including a stationary housing portion 109 and a deployable housing portion 111, it is noted that the configuration shown (e.g., shape, size, arrangement, etc.) is provided merely for illustrative purposes and shall not be construed as limiting the scope of the present disclosure. For example, the housing may be formed of deployable housing portion 111 (without a stationary housing assembly 109). It is noted that the stationary housing portion 109 may be formed of any suitable material such as, but not limited to, a plastic housing, metal housing, or any material that may be suitable for use on an aircraft.

[0049] In embodiments, the armrest attaching panel 122 may include a cushion (or cushioning layer) to provide cushioning to the auxiliary seat pan 115 when the deployable armrest assembly 108 is in the deployed position. For example, the armrest attaching panel 122 may include one or more layers of foam 124 (or other suitable materials capable of providing cushioning). For instance, as shown in FIG. 1E, the one or more layers of foam 124 may be positioned between a surface of the seat frame and a surface of the armrest attaching panel 122 when in the stowed position.

[0050] Referring generally to FIGS. 2-4E, the deployable armrest assembly 108 may include an actuator sub-system 120.

[0051] Referring to FIGS. 2-3D, the actuator sub-system 120 may include, but is not limited to, a locking assembly 201, an actuator 204, one or more brackets 208, a frame 210, a slot 211 within the frame 210, a rotation system (e.g., rod 212), a translation system 215, and the like.

[0052] The armrest attaching panel 122 may be coupled to the frame 210 of the actuator sub-system 120. For example, the armrest attaching panel 122 may be coupled to the frame 210 of the actuator sub-system 120 to allow the armrest attaching panel 122 to actuate between one of the stowed position or deployed position. For instance, a top surface of the frame 210 may couple to a bottom (or rear) surface of the armrest attaching panel 122. It is noted that the armrest attaching panel 122 may be coupled to the frame 210 via any fastening mechanism such as, but not limited to, welded, adhesives, fasteners (e.g., screws, bolts, etc.), and the like. In some embodiments, the armrest attaching panel 122 and the frame 210 may be integrated together (e.g., a single piece).

[0053] Referring generally to FIG. 2, the actuator sub-system 120 may include the one or more brackets 208 configured to attach the one or more deployable armrest assemblies 108 to the aircraft seat 102 via one or more base brackets 214. For example, as shown in FIG. 1B, when the aircraft seat 102 includes a single deployable armrest assembly 108, the one or more brackets 208 may be attached to at least one base bracket 214 positioned on a side of the aircraft seat 102. In one instance, the one or more brackets 208 may be coupled to the right side of the aircraft. In another instance, the one or more brackets 208 may be coupled to the left side of the aircraft.

[0054] By way of another example, as shown in FIGS. 1C-1D, when the aircraft seat 102 includes a plurality of deployable armrest assemblies 108, the one or more brackets 208 of the first deployable armrest assembly may be coupled to at least one base bracket 214 on a first side of the aircraft seat 102 and the one or more brackets 208 of the additional deployable armrest assembly 108 may be coupled to an additional side of the aircraft seat 102. In this regard, the first deployable armrest assembly 108 may be coupled to the right side of the seat pan 106 and the additional deployable armrest assembly 108 may be coupled to the left side of the seat pan 106, and vice versa.

[0055] Although FIG. 2 depicts the one or more base brackets 214 of the aircraft seat 102 positioned on a side of the aircraft seat, it is noted that the one or more base brackets 214 of the aircraft seat 102 may be positioned in any configuration on the aircraft seat 102 suitable for coupling the one or more deployable armrest assemblies 108 to the aircraft seat 102 via the one or more brackets 208.

[0056] The actuator 204 may be configured to actuate the deployable armrest assembly 108 between one of the stowed position and the deployed position. It is noted that the deployable armrest assembly 108 may be positioned in one or more intermediate positions between the stowed position and the deployed position when actuating between one of the stowed position and the deployed positioned, and vice versa.

[0057] The actuator 204 may include any type of actuatable suitable for actuating the deployable armrest assembly 108 between one of the stowed position and the deployed position. For example, the actuator 204 may include, but is not limited to, one or more electro-mechanical actuators, gas spring actuators, linear/rotary actuators, or the like. For instance, as shown in FIGS. 3A-3D, the actuator 204 may include a gas spring actuator 204. Although FIGS. 3A-3D depict a specific actuator sub-system configuration, it is noted that the actuator 204 may be configured in any manner suitable for actuating the deployable armrest assembly, as such FIGS. 3A-3D are provided merely for illustrative purposes and shall not be construed as limiting the scope of the present disclosure.

[0058] In embodiments, as shown in FIG. 2, the actuator 204 may be configured to couple to a portion of the aircraft seat 102 via one or more fastening mechanisms. For example, a first end of the actuator 204 may be coupled to the aircraft seat 102 via one or more fasteners 216 such as, but not limited to, one or more bolts, one or more screws, or the like. For instance, the first end of the actuator 204 may include an opening configured to receive the fastener 215 (e.g., bolt 216), where the bolt 216 may couple to a surface 217 of the aircraft seat 102.

[0059] In embodiments, as shown in FIG. 2, the actuator 204 may be coupled to the frame 210 via a rod 213 within the frame 210. For example, an additional end of the actuator 204 (opposite the first end) may include an opening configured to receive a portion of a shaft of the rod 213, where the rod 213 may be coupled to the frame 210.

[0060] The locking assembly 201 may have a locked state to prevent the actuator sub-system 120 from actuating (e.g., remaining in the stowed position). For example, the locking assembly 201 may prevent the deployable armrest assembly 108 from actuating during certain aircraft events (e.g., take-off, landing, or taxi) when the deployable armrest assembly should be kept in the stowed position. By way of another example, the locking assembly 201 may have an unlocked state to allow the actuator sub-system 120 to actuate (e.g., deploying the actuator sub-system 120).

[0061] The locking assembly 201 may include, but is not limited to, a latch 202, a release cable 203, a release lever 205, release mechanism 206, and the like.

[0062] The latch 202 may be coupled to the frame 210. For example, the latch 202 may include a rotary latch 202. The latch may include a mechanism, such as a release lever 205, that may move the latch form a locked state to an unlocked state.

[0063] The release cable 203 may be configured to unlock the latch 202. For example, the release mechanism 206 (e.g., control button, or the like) may be configured to pull the release cable 203 to cause the release lever 205 to unlock the latch 202. In this regard, the latch 202 may change from a locked state to an unlocked state by a user (e.g., the main passenger) engaging the release mechanism 206. For example, during non-TTL stages of the flight, the main passenger may engage (e.g., press, pull, and/or activate) the release mechanism 206 to change the state of the latch 202 from the locked state to the unlocked state. In this regard, when the release mechanism 206 is engaged and the latch 202 is in the unlocked state, the deployable armrest assembly 108 may actuate from the stowed position to the deployed position.

[0064] The translation system 215 may include one or more tracking rails 207 and one or more carriages 209 configured to translate along a vertical axis of the tracking rails 207. For example, one or more tracking rails 207 may be coupled to the internal side of one or more brackets 208 (e.g., the side of the bracket 208 oriented towards the frame 210) and the one or more carriages 209 may be coupled to the frame 210. In this regard, the carriages 209 may rest within the tracking rail 207 and be configured to translate along the vertical axis of the tracking rail 207.

[0065] The rotation system may include a rod 212 having one or more ends, with each end coupled to a respective bracket 208. For example, the slot 211 of the frame 210 may be configured to receive a portion of the shaft of the rod 212. For instance, as will be discussed further herein, a portion of the shaft of the rod 212 may rotate within the slot 211 of the frame 210.

[0066] Once the locking assembly 201 is in the unlocked state, the actuator 204 may apply force (e.g., a restoring force from a spring) to the frame 210. In embodiments, the actuator 204 may apply force to the frame 210 vertically along the translation system 215. The frame 210 may translate vertically, until the rod 212 comes in contact with the end of the slots 211 of the frame 210, as illustrated in 3B. As illustrated in FIG. 3C, the frame 210 may then pivot horizontally around the rod 212. The frame 210 may pivot horizontally approximately 90° until the frame is sustainably parallel to the aircraft floor in the deployed position (e.g., the deployable housing portion 111 sitting flush with the seat pan 106).

[0067] In embodiments, when the locking assembly 201 is in the unlocked state, the frame 210 may pivot horizontally approximately 90° and then translate vertically until reaching the deployed position (e.g., the deployable armrest assembly sitting flush with the seat pan 106). By way of another example, as shown in FIG. 5, the frame 210 may simultaneously pivot horizontally and translate vertically until reaching the deployed position.

[0068] Now referring to FIGS. 4A-E, FIGS. 4A-E illustrate the aircraft seat during actuation of the deployable armrest assembly 108 from the stowed position to the deployed position. In embodiments, the frame 210 may be coupled to the armrest attaching panel 122 so as the frame 210 actuates, the armrest attaching panel may simultaneously actuate. As illustrated in FIG. 4B, for example, as the frame 210 translates along a vertical axis via the translation system 215, the armrest attaching panel 122 may simultaneously translate vertically. For example, as the rod 212 translates within the slot 211 of the frame via the translation system 215, the armrest attaching panel 122 may simultaneously translate along the vertical axis. As illustrated in FIG. 3C, the armrest attaching panel 122 may rotate about a pivot point of the rod 212 until the armrest attaching panel 122 is substantially flush with the seat pan 106, such that the armrest attaching panel 122 is in a substantially horizontal position. For example, the frame 210 may rotate within the slot 211 of the frame 210 about a pivot point of the rod 212. For instance, the frame 210 may rotate approximately 90 degrees within the slot 211 of the frame 210 about the shaft of the rod 212 until the armrest attaching panel 122 is positioned in the deployed position and sits substantially flush with the seat pan 106 to form the wide seating area 116.

[0069] In embodiments, when actuating from the deployed position to the stowed position, the armrest attaching panel 122 may pivot about the pivot point in horizontal direction until the orientation of the armrest attaching panel 122 is vertical. The armrest attaching panel 122 may then translate down the vertical axis until reaching the stowed position.

[0070] In some embodiments, the deployable armrest assembly 108 may include an auxiliary seatback portion 114. For example, the auxiliary seatback portion 114 may be configured to actuate between one of a horizonal position to an upright position. In this regard, the auxiliary seatback portion 114 to be used by a companion when the auxiliary seat pan 115 is in the deployed position and being used as a buddy seat.

[0071] In embodiments, when the deployable armrest assembly 108 is in the deployed position, the auxiliary seatback portion 114 may pivot forward a certain degree determined by the design of the deployable armrest assembly 108, around a pivot point across the auxiliary seat pan 115.
